Just wanted to share some info on the injectors I had that were acting up.
I was attempting to start my new L&M engine after being down for an embarrassingly long time and only cylinder #5 would fire. Very frustrating of course but I stayed after it by checking for the 12v and signal within the fuel injector wiring, then pulling each plug to make sure I was getting spark and lastly checking each fuel pump with the feed line disconnected at the rail to make sure I had fuel. It still would not start so I fashioned up the ole 9v battery test and could hear that only one of the 8 "sounded" like it was opening and closing. I decided to remove them to take a visual that they were actually spraying and sure as chit only one injector was opening. After using a 10x to get a close up view of what was going on I could see that the needle valve on 7 of the injectors was not opening/moving despite the application of 9volts. After I gently depressed the tip they each began to function as you'd expect. (even the little bit of fuel inside each inj could be seen spitting out btw) I re-installed them and bam, she started right up and set into a mean idle. These were brand new (likely old stock) ID1000 injectors that were stuck closed. Although I was very happy at that point I was nudged by more than a few to get them cleaned and flow checked, which I begrudgingly did but I'm glad I finally calmed down and realized the consequences/risks and did so. A few injectors were down a fair amount. Definitely a confidence builder!
